22 OCTOBER 2007 -- COYOTE CANYON, NM: CHUCK MORGAN, a member of a construction crew, installs water pipes on the Navajo Indian Reservation near Coyote Canyon. The project is a part of an effort by the tribe's government to bring potable water to the members of the Navajo Nation. More than 30 percent of the homes on the Navajo Nation, about the size of West Virginia and the largest Indian reservation in the US, don't have indoor plumbing or a regular supply of domestic water. Many of these homes have to either buy water from commercial vendors or haul water from public wells. A Federal study showed that the total cost of hauling water was about $113 per 1,000 gallons. A Phoenix household, in comparison, pays just $5 a month for up to 7,400 gallons of water. The lack of water on the reservation means the Navajo are among the most miserly users of water in the United States. Families that have to buy or haul water use only about 15 gallons of water per day per person. In Phoenix, by comparison, the average water use is about 170 gallons per day. Photo by Jack Kurtz
